Things to Look for in Snap’s IPO Filing

The planned IPO of the parent company of Snapchat is the most anticipated tech offering in years. The rapid rise of the messaging app has made competitors such as Facebook and Twitter quake–but Snap has put few numbers to its popularity so far.

That is set to change with this week’s filing. The public offering document, called the S-1 filing, typically includes a plethora of data and metrics to wow potential investors and justify the company’s hoped-for valuation–between $20 billion and $25 billion in Snap’s case. Like other tech founders, Chief Executive Evan Spiegel could also pen a letter as part of the filing, providing his sweeping vision for the company.
